EDWARD W. WISE, OF CENTRALIA, WASHINGTON.

BOILER OR HOT-WATER HEATER.

Specification of Letters Patent.

Patented May 23, 1916.

Application filed November 19, 1913. Serial No. 801,942.

To all whom it may concern:

Be it known that I, EDWARD W. VVISE, a citizen of the United States, residing at lentralia, in the county of Lewis and State or Washington, have invented certaln new and useful Improvements in Boiler or Hot- W'ater Heaters, of which the following is a specification.

It is one or" the objects of this invention to provide a hot Water heater wherein a relatively small column or body of water can be quickly heated so as to avoid. the necessity of a heavy casing, which has been found to be necessary where attempts have been made to heat larger columns or quantities of water, the primary feature of the invention consisting in having an increased heating area or capacity in a relatively reduced space.

It is one of the special objects of my in: vention to provide means whereby relatively large bodies of cold water may be admitted, preferably at the intake, and subjected to a quick heating action prior to admission of such initially intaken bodies to the water tubes, thereby quickly raising the temperature from the normal water temperature of the supply, to a relatively high temperature prior to admission of the water into the tubes. 7

In connection with this feature of the inrelatively large water intake sides closely adjacent the grate, with the walls of the 1ntake sides adjacent the grate corrugated or otherwise formed to increase the heating area beyond the normal area of a flat Wall inclosing such water sides.

Other objects and features of the invcntion will be more fully described in connection with the accompanying drawings and will be more particularly pointed out and ascertained in and by the appended claims.

In the drawings :Figure 1' is a longitudinal vertical sectional view of the boiler or hot water heater embodying one form of my invention. Fig. 2 is a sectional view on line 22 of Fig. 1. Fig. 3 1s a sectional view on line 3-3 of Fig. 1. Fig. 4 is a sectional view, on line H of Fig. 1.

The device of my invention is inclosed in a casing of thin sheet material, as generally indicated at 1. An ash pit 2 is provided below the grate 3 and is divided by partitions 4.- to form a hollow base chamber 5. The casing is provided with a front above the grate 3 and their heating area for the most it is one of the objects to provide 2 When the wall (3 having a suitable fire door 7 and the ash pit is provided with any desirable form of draft door 8.

A deflector 9 serves to deflect the products of combustion upwardlythrough passageway 10, into a rear chamber 11. A flue 12 opens into the chamber 11 by means of dampers 13 and 14 which are of a construction similar to the construction shown in my prior patent dated Sept. 3, 1912, #1,087,391, and need not be described in detail.

Extending along the grate 3 and as shown above said grate, are base headers 15 and 16 which communicate laterally with water sides 17 and 18. The water sides 17 and 18 extend along the sides of the boiler and inner walls 19 are corrugated, to increase their efficient transmisinner walls to the and 20, facing the fire bed, as indicated at 21, so as sion of heat through said relatively large bodies of water which the water sides are formed to contain. I also prefer to make the inner walls 19 and 20 relatively thin, with respect to their other walls, and thereby further increase the effective transmission of heat to the incoming bodies of water in the water sides 17 and 18 so as to quickly heat the water to a temperature greatly in excess of its temperature when entering the water sides. Water intakes 22 and 23, and also water intakes may be provided for admission of water to the water sides from any suitable source of supply. One or more of the water intakes may be used in accordance with the conditions under which the boiler is operated. It will thus be seen that the incoming water will first be admitted to the base headers 15 and 16 and to the water sides 17 and 18 in close proximity to the fire bed.

The water sides 17 and 18 communicate at their upper portions and deliver to sets of superposed side headers 24 and 25. These side headers communicate with each other, as regards each set, and the side headers are connected by water tubes 26 which-extend horizontally across the space above the fire bed so as to be subjected to the highest possible temperature. The deflector 9 causes the products of combustion to pass upwardly from the fire bed so that they will play upon the tubes 26 and thereby cause the same to function as the primary generating tubes, when the boiler is used as a steam generator. boiler is used as a water heater,

the tubes 26 will be the primary heating tube. The uppermost header 25 may be provided with supply and return connections 27 and 28 for connection with the heating system with which the boiler is used.

Rearwardly of the fire bed, I provide a nest of water tubes 29, which are shown vertically disposed. Said tubes are connected with sets of top and bottom headers 30 and 31 which communicate with each other and also with said tubes 29, the upper headers, or one thereof, having a supply or return connection 32. Intakes 33 may be provided for the lower header 31. A connection 34: is provided between the upper headers 30 to the uppermost of the side headers 24: so that water or steam may circulate from the primary heating or generating tubes 26 through the tubes 29 and their headers. The circulation through the tubes 29 is provided only at the top of the headers 24:, at one side of the boiler, so that only the steam or water of the highest temperature will reach the upper headers 30. By reason of the deflector 9, the products of combustion in their passage from the fire beds about the tubes 26, will play efiectively on the tubes 29 so that the latter may constitute reservoir tubes for holding a considerable quantity of water which has been heated in the primary tubes 26 for supply to the system through outlet 32.

It is one of the features of this invention to provide interchangeable headers whereby a large stock of headers, for each size of the boiler to be assembled, can be kept on hand so as not to require special fittings for each boiler of different sizes. The headers 21 and 25 will be interchangeable, and likewise the headers 30 and 31.

It is believed that the utility and advantages of the invention will be fully understood from the foregoing description, and while I have herein shown and described one specific form of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.

I claim 1. In a boiler or hot water heater, a casing, a grate mounted low down at one end of said casing, intake water sides placed above and along the grate, side headers mounted on said water sldes to extend up as the sides of the fire box, tubes extending transversely across between said headers and arranged between said upper and lower headers, means connecting the upper header of said vertical tubes with one of the side headers, and a deflector mounted adjacent the vertically disposed tubes on the side away from the disposition of the grate to cause theproducts of combustion to be directed to and over the tubes.

2. In a boiler or hot water heater, a grate, intake water sides extending above and along the grate, superposed side headers communicating with each other and with the upper portions ofsaid water sides, tubes extending transversely across and above the grate and connected with said side headers, vertically disposed tubes arranged in the path of the products of combustion passing from said grate, upper and lower headers connected with said vertical tubes, and means connecting the upper headers of said vertical tubeswith one of the side headers.

3. In a boiler or hot water heater, a fire box, a grate mounted in said fire box, intake water sides located along the side walls of the fire box on either side of said grate, water inlet openings, inlet water connections located at a point low down in said intake water sides, a plurality of superposed side headers mounted above each of said intake water sides and communicating with each other, a plurality of water tubes connected with the oppositely disposed side headers and extended transversely of and above the grate, an outside casing within which said structure is inclosed, upper and lower headers arranged in horizontal dispositions in said casing at points beyond and on the flue side of the heating arrangement as hereinbefore described, a connection between one of said headers and one of said superposed side headers, a plurality of vertically disposed tubes mounted between said horizontally positioned headers, and a water outlet from one of said last-named headers.

In testimony whereof I aflix my signature in presence of two witnesses.
